Should I fear my charger could be confiscated? I'll be traveling through HK, Beijing, Siem Reap, Tokyo
China will take any battery that's unmarked. Otherwise, the limit is 100Wh. Watts = Amp * voltage. An ordinary charger battery is 5V, thus your 6,000 mAh = 30Wh. That should not be a problem anywhere but note about China wanting it to be marked. (Otherwise people would erase the markings and claim it was under the limit. Easier to say "must be marked" than resolve the borderline cases.)
